What didn’t the UV camera show sun damage?
You bring up a good point which is that lab tests, cameras, computer imaging, etc can all be in error sometimes or just not functioning well that day.

You can also see the melasma article – just ignore the hormone section – everything else about prevention and treatment applies. Dr. I
